# NOTE: THIS IS A LOCALIZED VERSION - CONTAINS REFERENCE TO AUTOLOADER THAT DOES NOT MATCH DEFAULT INSTALL

# jess whyte, @jesswhyte Aug 2018 

# usage example : bash nimbie.sh /media/storage/Nimbie_ISOs/
# you have to request and download linux SDK from Acronova
# make /64/autoloader executable

## jess notes: continue points = not iso, blank blocksize or blank blockcount or dd status != 0
## jess notes: autoloader status on LOAD, +s14 = no disk there [DONE WITH PILE], +s07 = OK, + s10 = drive closed, + s12 = disk already in
